PURPOSE:To improve the rigidity of a mount member by arranging an exhaust pipe along the under surface of the mount member to effectively utilize a dead space in an engine room. CONSTITUTION:A center member 19, which functions as a mount member to support a power unit 18 comprising an engine 16 and a transmission 17, is connected between the primary cross member 15 and a dash cross member 10 in the longitudinal direction of a car body. A lower part of a flexible pipe 22 in a front exhaust pipe 23 is conducted under the center member 19, and in addition to that, the front exhaust pipe 23 is arranged along the under surface of the center member 19, and both of them are unitedly fixed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention provides a first cross member extending in the vehicle width direction and a second cross member extending in the vehicle width direction.
The present invention relates to a power unit support device for a vehicle in which a mount member on which a power unit is placed is connected between a cross member and a mount member.

(Prior Art) Conventionally, as a power unit support device for a vehicle of the above-mentioned example, there is a device described in, for example, Japanese Utility Model Application Publication No. 60-49019.

That is, this is a device in which a mount member is connected between a first cross member and a second cross member extending in the vehicle width direction, and a power unit is supported on the mount member.

However, in the above-mentioned conventional structure, the location of the exhaust pipe is not specified, so if the above-mentioned exhaust pipe is arranged above the engine mount member, the capacity 1 engine room space such as the oil pan etc. There is a problem that the exhaust pipe described above is restricted, and if the exhaust pipe described above is placed below the mount member, there is a problem that a reinforcing member is required separately to improve the rigidity of the mount member. had.

(Purpose of the Invention) This invention effectively utilizes the dead base in the engine room to arrange the exhaust pipe, so that it is not affected by the container or space of the oil pan, etc., and the reinforcing member It is an object of the present invention to provide a power unit support device for a vehicle that can improve the rigidity of a mount member without requiring the same amount.

(Structure of the Invention) The present invention includes a first cross member located at the rear end of the engine room 3 and extending in the vehicle width direction, a second cross member located at the rear end of the engine room 3 and extending in the vehicle width direction, Extending in the direction - (- connecting the F-registered cross members,
The present invention is characterized in that the present invention is a power unit support device for a vehicle, comprising: a mount member that supports a power unit; an exhaust pipe is disposed on the lower surface of the mount member; and the exhaust pipe is coupled to the mount member.

(Effects of the Invention) According to the present invention, since the above-mentioned exhaust pipe is arranged on the lower surface of the mount member, dead space in the engine room can be effectively used, and as a result, the capacity and space of the oil pan etc. are affected. It will not be possible to receive one.

Moreover, since the above-mentioned exhaust pipe is connected to the lower surface of the mount member, there is an effect that the rigidity of the mount member can be improved without requiring any special reinforcing member or the like.

(Example) An embodiment of the present invention will be described in detail below based on the drawings.

The drawing shows a power unit support device for a vehicle, and in FIG.
A radiator 4 is disposed inside, and a bonnet 5 is provided to cover the upper opening of the engine room 3 in an openable and closable manner.

On the other hand, at the front end of the floor panel 6 is a darts lower panel 7.
is fixed upright, and the dash upper panel 8 and cowl panel 9 are joined to the upper end of the darts lower panel 7, and the lower end of the darts lower panel 7 has a linear cross section and is located at the rear end of the engine compartment 3. The dash cross members 10 are joined to form a closed cross section 11. .

At the lower part of the radiator 4 mentioned above, a first cross member 15 is provided which forms a closed cross section 14 by joining two members 12 and 13 and is located at the front end of the engine room 3.
The O-stand bar 15 is provided to extend in the vehicle width direction, and the aforementioned dash cross member 10 as a second cross member is also provided to extend in the vehicle width direction.

A center member 19 serving as a mount member for supporting a power unit 18 including an engine 16 and a transmission 17 is connected between the first O standbar 15 and the dash cross member 10 in the longitudinal direction of the vehicle body. There is.

As shown in FIGS. 2 and 3, this center member 19 is a member with a hat-shaped cross section that is open at the bottom, and is attached to each of the aforementioned cross members 10, 15 using a plurality of bolts, nuts 20, etc. It is installed.

By the way, as shown in FIG. 1, a front exhaust pipe 23 is connected to an exhaust passage 21 including an exhaust manifold of the engine 16 via a flexible pipe 22 for absorbing vibrations.

Connect the lower part of the flexible pipe 22 to the front exhaust pipe 23 to the above-mentioned center member 19.
The front exhaust pipe 23 is led out to the lower surface of the center member 19 through the opening 24, and the front exhaust pipe 23 is arranged along the lower surface of the center member 19.
9.23 are connected and fixed by arc welding means as shown in FIGS. 1 and 3.

A catalytic converter, a middle exhaust pipe, a thigh sensor, etc. (all not shown) are connected to the rear end of the front exhaust vibe 23 joined to the lower surface of the center member 19 described above.

The above-mentioned engine 1
6 and a transmission 17 are mounted and supported on a center member 19 and left and right front frames (not shown).

As described above, the front exhaust pipe 23 is arranged along the lower surface of the center member 19, and the front exhaust pipe 23 is arranged at the same position as the center member 19. The dead space in the engine room 3 can be effectively used to provide layer resistance without having to be installed above the engine mount member, and as a result, the space for the oil pan, etc. is no longer affected. Things will disappear.

Moreover, since the above-mentioned front exhaust pipe 23 is coupled and fixed to the center member 19, there is an effect that the rigidity of the center member 19 as a mount member can be improved.

In the correspondence between the structure of this invention and the embodiment of (a) E, the second cross member of this invention corresponds to the dash cross member 10 of the embodiment, and similarly, the mount member corresponds to the center member 18. Although the exhaust pipe corresponds to the front exhaust pipe 23, the present invention is not limited to the configuration of the above-described embodiment.
